Thailand eSIM guide: local networks, airport SIM costs & setup

Why roaming and airport SIMs cost more in Thailand

European and North American home SIMs bill Thailand as rest-of-world roaming. Leaving data roaming on with your home carrier can trigger a 50 € data cap within minutes.

At Suvarnabhumi (BKK) and Phuket (HKT), arrival kiosks require passport scanning and a photo of the buyer, with long queues when several wide-body flights land together.

With a prepaid Thailand eSIM from 5.49 € incl. VAT (custom & group plans — price negotiable), you receive the QR code and iPhone direct-install link right after payment.

4-step setup on iPhone and Android before you fly

Check that your phone is unlocked and supports eSIM by dialling *#06# — if an EID number appears on screen, your phone has an eSIM chip.

Install the profile over home Wi-Fi the day before departure. Keep the travel eSIM line switched off until you land, then enable it for Mobile Data with Data Roaming turned on for the travel eSIM (and Data Roaming turned off on your home SIM).
